Compressive Strength Test on Concrete . Procedure Representative samples of concrete shall be taken and used for casting cubes 15 cm x 15 cm x 15 cm or cylindrical specimens of 15 cm dia x 30 cm long. The concrete shall be filled into the moulds in layers approximately 5 cm deep.
control of several parameters related to the productive process for the compressive strength of the units. Keywords: mix design, concrete block, dry concrete, vibrocompression machines INTRODUCTION The production of concrete blocks used in both structural and cladding masonry is characterized by the use of "dry concrete".
This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ].
METHOD OF TEST FOR COMPRESSIVE STRENGTH OF MOLDED CONCRETE CYLINDERS A. SCOPE This test method covers the procedure for compression tests of molded concrete cylinders. It is a modification of ASTM C39/C39M and AASHTO T 22. ... Place the test specimen on the lower bearing block.
Compressive strength is an effective way of measuring how much load a surface or material can bear. The test for this sort of strength is performed by exerting force downward on top of the object, paired with an equal and opposite force exerted upward on the bottom.

Compressive Strength of Concrete Cubes – Lab Test Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

Rebound hammer test is done to find out the compressive strength of concrete by using rebound hammer as per IS: 13311 (Part 2) – 1992. The underlying principle of the rebound hammer test is. The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes.
A compressive axial load is applied to molded cylinders or cores until failure occurs. The compressive strength of the specimen is calculated by dividing the maximum load achieved during the test by the crosssectional area of the specimen. The results of this test method are used as a basis for quality control of concrete.
